Page, head of the Saint Louis Airplane Division of Curtiss-Wright, decided to develop a fighter aircraft based on Carl W. Scott's two seater Model 19. Page's concept was a lightweight fighter interceptor with as high a rate of climb as possible in order to allow bomber formations to be attacked with minimal warning. If faced with fighter opposition, it was intended not to dogfight, but to use its superior climb rate to escape.〔Casius 1981, pp. 33–34.〕 While this was a direct contradiction to the United States Army Air Corps′ requirements for fighters (which stressed low-level performance), this did not concern Page, since the new fighter was intended for export.〔Casius 1981, p. 34.〕〔Angelucci and Bowers 1987, pp. 153–154.〕 Detailed design of the new fighter, the Model 21, or CW-21, was carried out by a team led by chief engineer Willis Wells. It was a single-seat, all-metal cantilever low-wing monoplane with retractable tailwheel landing gear, where the mainwheels retracted rearwards into fairings under the wing. The fuselage was a semi-monocoque structure that tapered sharply behind the pilot's cockpit. It was powered by a Wright R-1820-G5 nine-cylinder air-cooled radial engine. It was designed to carry various combinations of two or s, mounted in the nose and synchronized to fire through the propeller, while no armor or fuel tank protection was fitted in order to save weight and hence improve performance.〔〔Bowers 1979, p. 431.〕 The prototype first flew on 22 September 1938, carrying the civil experimental registration ''NX19431''.〔 Although the CW-21 was not commissioned by the U.S. military, it was test flown at Wright Field in Dayton, Ohio. The Army Air Corps immediately rejected the aircraft, with one officer commenting that it took a genius to land it.〔Edwards 1992〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Curtiss-Wright CW-21」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
